As best shown in Fig. 1, the ends of the side. members fO-l of the baseare beveled or inclined after the manner of runners, so that the. baseforms in effect a sled on which the apparatus may be moved from place toplace. [n order to form a secure and stable support which will becapable of enduring the rough treatment to which it is subjected inbeing hauled about, I provide corner-plates 33, one for each corner ofthe base, which plates are eountersnnl; on their upper sur I'aces orareprovided with marginal llanges 34, as shown in Figs. 13, 14 and 15, sothat the lower ends of the posts 24 to 27 may be tted in them andthereby held firm against. displacennfnt. as shown in Fig. ll. Saidcorrnir-plates rest on the members lf2-23 of the base, and bolts 35,which pass through both members of the base and the superimposed post,serve to hold the parts fixedly together. 'lhis is well illustrated inFig. 11, from an inspection of which it will be seen that the bolt 35passes up through the side member 21, the overlying end member 22, thecornerplate 33, and the post 27. The base is further st-rengthened bymeans of braces 36, 37, 38 and 39, the ends of which are looped, asshown at 40 in Fig. 15, and fit in suitable recesses 41 provided in thecorner-plates, as shown in Figs. 13 and 15. Said recesses are arran eddiagonally to accommodate the diagona arrangement of the braces, asshown in Fig. 10. The braces are connected at the center of the base bymeans of a bearing plate 42 in which the lower end of the mast isstepped,said plate having hooks 43 at suitable points in its eriphery toengage suitable loops provided at the inner ends of the braces, as shownin Fig. 5. If desired, any other suitable means may be provided fortightening the braces. By fitting the outer ends of the braces in therecesses in the corner-plates, as described, said plates in themselvesserve as anchors for the braces, so that the strain is not appliedwholly to the bolts ln fact, the parts may be arranged so that theentire strain is taken by the cornerplates. By the constructiondescribed the members ol' the base and supporting frame are iirmlysecured together, making it practically impossible for them to spread atthe bottom, and a very light but strong base is secured.

43l indicates stake loops provided at the corners of the base, as shownin Fig. 5,- said loops being pivotally connected 1n any suitable waywlth the members of the base.

44, 45, 46 and 47 indicate angleirons bent to substantially U shape, asshown in Fig. 1, which serve to secure the posts 24,25-26- 27 togetherat. or near their upper ends, as best shown in l `igs. (i and S. Saidangleirons also serve. to support the turntable 48, which is also ananfleiron bent to circular form, as -shown in Figs. (i and `8,--thehorizontal fiange resting on the angleirons 44 to 47 while the verticalfiangc fits inside of said angleirons and is lixedlj secured thereto inany suitable manner as by rivets or bolts. l thus provide horizontal andvertical tracks for suitable rollers carried by the mast, as hereinafterdescril'ied.

The members '2.8-2.9 of the mast are seta distance apart, being fartherapart intermediately than at their ends. At their lower end` they areconnected b v means oll a block Vlit which also serves as a pivot,being' provided with a downwardly-projecting end 5t) which fits into thebearing plate 42. Said block is provided with suitable recesses 5l toreceive the, lower ends of the members of the mast and with a rib 5;),which projects beyond the members of' the mast, as shown in Fig. 1, andis provided with holes 53 to receive the lower end of a brace 54, theupper end of which is connected with a hand-lever or sweep 55, as shownin Fig. 1. The inner end of said sweep projects between the members ofthe mastand is fixedly secured in place, being further secured by sidebraces 56, as shown in Fig. 1. The block 40 is also provided with a hook57 to receive a pulley 58. lntermediately the members of the mast areconnected by a casting 59, as shown in Figs. 6, 7 and 8. Said castingnot only serves to unite the members of the mast but also supportshorizontal and vertical pivots 60-61. for rollers (i2-63, respectively,which run on the horizontal and vertical flanges of the turntable ortrack 48, as shown in Fig. 7. The casting 59 also carries a strut 64over which extends a truss-rod connecting the end portions of the mast,as shown in Figs. 1 and 9, and opposite said strut it carries a yoke 66which is adjacent to and preferably a continuation of the pivot- GO.Said yoke serves to support the inner' end of a jib G7, which will behereinafter described, as shown in Figs. 1, 7 and 8. ln addition to thecasting 59 a number of additional braces are. provided for the. membersof the mast, as shown at (57, G8 and G9 in Fig. 4. 70 indicates a braceconnectiim the outer portion of the strut. (i4 with the brace t.

At itsl upper end the mast carries a pulle 7l, as best shown in Figs. 1and 4. lt also carries a swinging support 72 on which is mounted apulley 73, as shown in Fig. 1.

74-75 indicate beveled bearing blocks op positely disposed and securedto the members '28*29 of the mast, as shown in Figs. and S. Said blocksare arranged so that their outer margins are adjacent to the verticaltrack, and they serve as buffers to hohl the. mast substantiallycentral.

The pointe of the fork teeth are' protected bywrought iron gi'iards or shoes 83 which fit nfpon the ends of the teethand are seemed! by rivets or bolts S4, as shown in Fig. 18. Said shoesare simply stra-p iron bent to suitable' shape and fitted to the upperand lower surfaces of the forli, teeth, als" sllit'wvn in Fig. 18, areinclilite'd. nipward and backward.. ais shown, so that when theI hayraked niponf the fork of the stacker bv means of a horseralte if theteeth of the fork strike the' teeth of thev stacker they will be thrownup without doing any substflne tial damage. For the same reason theforward edge of' the' crossbar 80, shown in Fig'.y 16, is beveled.
